How to Use
This guide was prepared to assist in the selection of current replacement types for foreign and domestic industrial receiving tubes. The first column lists in numerical-alphabetical sequence the type designation of the industrial receiving tube types to be replaced. The next two columns give the RCA Replacement Types. The column under the heading "Direct" gives direct replacements for the type in the left hand column. The column under the heading "Similar" gives the types that are similar in many respects to the type to be replaced but which are not directly interchangeable because of differences in mechanical and/or electrical characteristics. For more information as to the degree of interchangeability of "Similar" types, refer to the data for the respective tube types.
Types replaceable only by themselves are not included.

SAFETY PRECAUTIONS
In servicing a television receiver that requires a replacement picture tube, a tube with the same type number or an RCA recommended replacement tube type should be used to assure the same or improved integral x-radiation shielding and implosion protection.
Note: For additional Safety Precautions, refer to page 93.
